Buderus G115 boiler faulty radiators


I have a Buderus G115 boiler & now it is approximately five years old. From last night, I am not getting the required hot water. I instantly doubted that radiators had some problem. When I checked them, I noticed that one radiator is extremely hot at the bottom & cold at a top. How can I fix it at home?



Hi Rob,

Your problem regarding radiator is might be because of air-buildup, rusty pipes or a problem with the central heating pump like the required hot water is not circulating properly. It is recommended to bleed the radiators but, with the help of skilled boiler engineer in order to remove the trapped air. In case, it does not solve the issue of heating, power flush is mandatory.
